       IPv4 Traffic Offload Selector Option for Proxy Mobile IPv6
              draft-ietf-netext-pmipv6-sipto-option-06.txt

Abstract

   This specification defines a mechanism and a related mobility option
   for carrying IPv4 Offload traffic selectors between a mobile access
   gateway and a local mobility anchor in a Proxy Mobile IPv6 domain.
   Based on the received offload flow selectors from the local mobility
   anchor, a mobile access gateway can enable offload traffic rule on
   the selected IPv4 flows.

1.  Introduction

   Mobile Operators are expanding their network coverage by integrating
   various access technology domains (Ex: Wireless LAN, LTE) into a
   common IP mobile core.  For providing IP mobility support to a mobile
   node irrespective of the access network to which it is attached.  For
   example, the 3GPP S2a Proxy Mobile IPv6 [TS23402] reference point,
   specified by the 3GPP system architecture, is providing the needed
   protocol inter-working.  When this protocol interface based on Proxy
   Mobile IPv6 [RFC5213] is used, the mobile node is topologically
   anchored at the local mobility anchor [RFC5213] in the home network.
